NEXT-100 Pressure Vessel Progress to Date

Vessel Design simplified, Material chosen.

Torispheric heads identical - 4 nozzles each - extra capacity Head nozzles shortened - extensions will be used as needed Nozzle extensions and cover plates contain O-ring grooves and pumpout ports

Manufacturer chosen - Movesa , Madrid

Site visit Fall 2011 - one other mfr. visited Capable and versatile mfr. - boilers, reactors for food and pharmaceutical, turnkey processing systems Separate facilities for stainless steel vs carbon steel Convenient for frequent vists during fabrication

User Design Specification Completed (ASME)

Specifies all vessel requirements and operating conditions Now goes to Mfr. and Certifying Authority for review and approval

• Mfr. will recalculate - final design must be agreed upon

Head thickness may meet EU code, but not ASME
